Publisher's blurb: Every so often, a strange comet passes over Toril. Sages have tried to predict when and where it will pass. But Yerg’s Comet, much like the effect it has on Faerun magic, is unpredictable. In this standalone adventure for a party of four 3rd level characters, everyone exposed to the odd power of Yerg’s Comet develops magical ability and becomes a spellcaster (albeit a very inconsistent one). Normally this isn’t an issue, but this time it passed over Sir Ignatius School for Wayward Youth. The boys there are already a handful without being able to cast magic missile. Oh and as if that wasn’t enough did we mention that someone managed to summon a Yeti?
